Dear Michelle, there are few words that can comfort you in this very stressfull [and awful] situation. It sounds like the aggressiveness of your Mother's cancer was beyond anyone's control. Even with all of your questioning, it is doubtful there was much to be done. Having to deal with your Dad's heart problem as well has got to be incredibly hard for you and your family. The only thing know to say to you is that 70 plus years on this earth of living and loving mean alot- keep that thought close to your heart. Amy
